[LaravelFreelancerNL]

My Environment

• ArangoDB Version: 3.12.0-1
• Deployment Mode: Single Server
• Deployment Strategy: Manual Start
• Configuration: default, no root pw (local dev)
• Infrastructure: own
• Operating System: Windows 11 with WSL/Ubuntu 20.04
• Total RAM in your machine: 64GB
• Disks in use: SSD
• Used Package: Ubuntu .deb

Component, Query & Data

Affected feature:
web interface

Steps to reproduce

1. Purge arangodb 3.11 (or just update, the result is the same)
2. Install ArangoDB 3.12 within WSL2, no root pw setting
3. Login with root
4. Select _system db
5. wait for the fails

Problem:
Several errors occur:

1. DB: could not fetch database
2. Network tab shows several requests failing:

• job (net::Err..)
• user (net::Err..)
• root (net::Err..)
• fontawesome webfonts

3. click on databases:

• Error shown: Failure: got unexpected server response: 11: not authorized to execute this request
• databaseDefaults request fails (401)
• database requests fails (401)

Expected result:
The UI to work properly.

I've posted a video of the sequence described here in the general slack channel. (The video was too large to attach to this issue).

(upon purging 3.12 and reverting to 3.11 everything works fine)
